[Amps] HV rectifier strings - to bypass or not?

I'm getting ready to lay out the HV rectifier board for my YC156 
project, and it occurs to me to wonder if anyone has ever really heard 
HV rectifier "white noise" in the receiver? It would be simpler to 
forget about the per-diode bypass caps and just bypass the output as it 
leaves the board. The supply will be housed in a separate cabinet from 
the RF deck, but connected of course with bypassed leads for HV, (SHV 
connectors) 110VAC and control signals.

My current intent is to use 8 6A10 diodes per leg. The transformer is a 
3KV, 2A CCS Peter Dahl and the filter is 32uF by means of two new 16uF 
7500V oil-filled caps from Henry Radio via eBay.

Opinions?

Thanks,
Jim N7CXI
